Question Memory Slot A1 not working

[3lwa_98]

Specs
Ryzen 5 5600x
Ram 2x8 Ballisitc crucial (DUAL CHANNEL)
B550M S2H gigabyte (2 ram channels only
Antec atom 650 W
RTX3060 TI GIGABYTE

First my PC WAS crashing while gaming with buzzing sound and BSOD's then i thought without inspecting it was ram or motherboard issue so i replaced both !!

then i had same issue typically then i tried to use single ram channel on B1 ONLY ands WORKS PROPERLY nearly month then i tried swap the same ram on A1 Channel slot then suddenly the crashing returns within 5 minutes playing So i expect a faulty RAM SLOT A1

my question should i expect another faulty Motherboard even replacing with a new one (Faulty Ram Slot) or it even a rare case and should look for another hardware components like CPU that make crash with channel A1 ONLY and could a faulty CPU communicate with one ram channel only B1 i don't know how CPU communicate with 2 channel ram ?

This motherboard?

Verify that found the applicable User Manual.

Refer to the manual to double check all connections and configuration settings.

Then, on Pages 9 and 10 take a closer look at 1-4 "Installing the Memory"

From Page 9:

"Dual Channel Memory Configuration This motherboard provides two memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual Channel memory mode will double the original memory bandwidth. "

What happens if you run the same test with the other stick of ram?

What happens if you run the same test with the other stick of ram?

Same case works on B1 and crashes on A1

Same case works on B1 and crashes on A1

It would seem that something is going on with the a1 slot.
